The libraries included here are the original packages, unpacked, and
with their version number removed from the directory name (for version
information, see the README files in the directories).
Certain files and subdirectories of the original library packages that
are irrelevant to Qt may not be included here. Typically, those are
the standalone library configuration and make files, tools, test
files, contribs, documentation, and similar.
Patches may have been applied, typically for configuration and build
issues in the Qt framework. Such patches can be reviewed in the the
public git repository; they will appear in the commit logs of each
library directory, following the latest clean version update commit.
The 'patches' subdirectory contains certain patches applied prior to
the start of the public git history, where the library has not been
updated since.
